15 checks and profiles

Primary shaping

Casting, metal additive manufacturing, and declared molding, powder and additive operations.

Casting

PRU-012Heuristic screen

Draft angle missing

Warn on interior vertical walls that appear to have zero casting draft.

View check

PRU-025Heuristic screen

Undercut

Flag internal concave features that prevent single-direction mold extraction.

View check

PRU-270Declared input

Selected rigid tooling withdrawal needs review

Signed outward-normal projection at selected planar interior points for explicitly declared rigid tooling withdrawal. INFO for immediate local interference; tangency and uncertainty unassessed. No complete tool sweep, ejection or manufacturability conclusion.

Metal additive

PRU-015Heuristic screen

Overhang needs support

Warn on downward-facing planar surfaces below the common 45deg self-support limit.

View check

PRU-016Heuristic screen

Build-plate warping risk

Warn on thin, wide flat bases that are prone to peeling from the build plate.

View check

PRU-037Heuristic screen

Horizontal hole unsupported

Flag horizontal holes >8mm diameter that will sag during metal printing.

Declared molding, powder and additive operations

PRU-150Declared input

Molded rib too thick

Measured straight rib thickness >60% measured adjacent wall thickness.

View check

PRU-151Declared input

Molded rib too tall

Measured straight rib height >3x measured adjacent wall thickness.

View check

PRU-152Declared input

Draft below selected texture requirement

Selected planar wall draft magnitude <3 degrees PM-T1 or <5 degrees PM-T2 relative to declared pull axis; no extraction/undercut claim.

View check

PRU-153Declared input

Printed SS316L hole too small

Selected full cylindrical void diameter <2mm for declared Materialise SS316L metal LPBF.

View check

PRU-154Declared input

Declared powder exit too small

Selected powder-exit full cylindrical void diameter <3mm; no cavity connectivity or powder-removal proof.

View check

PRU-155Declared input

Net-shape hole crosses pressing direction

Declared ASCO conventional ferrous press/sinter; selected full cylindrical void intended net-shape is not parallel to pressing axis; secondary machining needed.

View check

PRU-156Declared input

Pressed sleeve too slender

Declared ASCO conventional ferrous uniform sleeve; exact tube axial height exceeds 8x measured radial wall thickness, density/tooling risk screen.

View check

PRU-220Declared input

Declared cavity has no selected exit path

Capped analytic passages and classified void components prove only geometric reachability from explicitly selected internal points; no powder-flow or evacuation certification.

View check

PRU-221Declared input

Local blow-mold width-depth guidance

Custom-Pak PE/PP declared mold-half role and pair: exact local rectangular mouth/floor/four-wall topology; minimum mouth width versus local mouth-level depth. INFO supplier guidance only.
